Summer Phoenix says there's little she wouldn't do to land the right role - except, that is, for eating meat and having sex. Here, River and Joaquin's baby sister talks to Polly Vernon about making her own name and how a vegan with family values copes with Hollywood.

Ten years ago, River Phoenix collapsed and died from a drug overdose. He was 23 years old, and the brightest in a generation of Hollywood actors that included Brad Pitt, Johnny Depp and Keanu Reeves. But where others have been made more famous by dying young, Phoenix's star has fallen. Why? Ryan Gilbey asks the actor's friends and colleagues where, if he had lived, he would be today

He's been a vegan since he was three, doesn't have a telly and has an entourage of one. He's not exactly conventional Hollywood, but then nothing about Joaquin Phoenix is as it seems. Even his first leading role - a drug-pushing US soldier - is ruffling the feathers of American hawks. Sanjiv Bhattacharya meets River's little brother.
